Product Overview

Layered double hydroxides (LDHs) are 2D hydrotalcite materials consisting of a positively charged main layer and exchangeable interlayer anions. Generally, it can be expressed as [M2+1-xM3+x(OH)2]x+[(An-)x/n]x-·mH2O (M2+ and M3+ are bivalent Ni2+, Co2+, Fe2+ and trivalent metal ions Al3+, V3+ and Cr3+, respectively, and An- is an interlayer anion (carbonate and nitrate). x is the molar ratio of M3+/(M2++M3+). For the preparation of LDHs, the main preparation methods include chemical precipitation, hydrothermal method, solvothermal method and so on. 1. The chemical precipitation method uses homogeneous chemical precursors as the substrate material, in which two or more metal ions are intricately mixed together and produce synergies to form the desired material. The main preparation process is to dissolve the bivalent and trivalent metal nitrate chemicals in deionized water with a certain molar ratio, and stir for a period of time at the appropriate temperature (generally 60 ° C), and then add the NaOH solution drop by drop and maintain the pH of the solution at about 10 ~ 11, stir for a period of time, and place it at the appropriate temperature after aging. 2. Hydrothermal method is usually used to enhance the crystallinity of layered double hydroxides. Hydrothermal method can obtain well-crystallized and evenly layered double hydroxides. The main preparation process is to mix the bivalent and trivalent metal nitrate chemicals and urea in aqueous solution to form a homogeneous solution in a certain ratio, and then add it to the reaction kettle for the corresponding time to prepare. 3. Solvothermal method is a simple and environmentally friendly method. Similar to the hydrothermal method, the difference is that hydrothermal is to mix two metals in an aqueous solution to form a homogeneous solution, while solvothermal is to mix two metals in an organic solution to form a homogeneous solution, and then put it into the reactor at a higher temperature reaction preparation.

Product Features

 

Adjustability: Suitable metal ions can be selected according to the needs of the catalyst for type or quantity modulation, so as to obtain different functions of LDHs.

Structural memory effect: LDHs can be converted into relatively stable bimetallic oxide LDOs under high temperature roasting conditions, which has good thermal stability and multi-layer pore structure, and has been widely used in the field of electrochemistry.

Strippable layer and assembly: The interaction force between LDHs laminates is relatively weak, and it is easy to be destroyed by external forces, and it is stripped into a single-layer nanosheet structure.

 

Application Fields

 

 

Electrolytic water oxygen/hydrogen evolution reaction: LDHs containing transition metal ions Fe, Co, Ni, Mn, etc., is a good OER catalyst. For example, NiFe LDHs is one of the catalysts with the best OER properties, and is also considered to be a promising non-precious metal based OER electrocatalyst. LDHs can effectively adsorb hydroxyl species, such as CoNi-LDHs has good HER activity under alkaline conditions, and its activity is much higher than Ni(OH)2 and Co(OH)2.

Biomedical field: Good biocompatibility, low toxicity, lamellae structure can accommodate biomolecules, such as the use of CoMn-LDH nanosheets loaded with photosensitizer Ce6 for photodynamic/chemokinetic synergistic therapy to inhibit tumor growth.

Ion adsorption: Due to the special layered structure of LDHs and the strong ion exchange characteristics of interlayer anions, LDHs materials are usually used for the adsorption of heavy metal ions in sewage, such as selenium (VI), arsenic (III, V) and so on.

Supercapacitors: Layered metal hydroxide is a typical Faraday pseudocapacitor material, which has a high theoretical specific capacitance and is a promising electrode material for supercapacitors. LDHs has a large specific surface area, more active sites and a short diffusion distance, which facilitates the rapid migration of ions between the nanosheet surface and the electrolyte, thus significantly improving the Coulomb efficiency of the device.

Simple AND essential, everyone should read
Format: Kindle
I've been Christian for many years, reading many books, sermons, biblical readings, but we never stop having more beautiful insights of this glorious Christian path laid before our minds and hearts. This book is a wise, beautiful, encouraging, and simply amazing way to see and live out the Christian life and calling, rich with meaning in our current broken world and the redeemed and restored world in Christ. Are you yearning for real spirituality, joy, justice, beauty, relationships, but they seem somehow out of reach? Read this book. It is simple yet profound. Take the time to savor the words of this book alongside prayer, biblical reading, community, daily work...And partake in the overlap of heaven and earth with the Lord.

Why "Simply Christian" is a "must read"
It presents a compelling case for Christianity without attempting to bully the reader (as C. S. Lewis often does in his essays) and without relying on all those "code words" that long-time Christians find familiar but others do not. This is the Gospel in plan English. Bravo! It firmly insists that Christianity makes claims about history - that Jesus lived, died, and rose again, and that this resurrection is the central event in the story of God's re-creation of our fallen world. It insists that Christians be active participants in the future unfolding of God's plan. We are each called to play a unique role in it. It insists that there is a transcendent realm, another world, that can and does intersect or overlap with our own world, especially in sacraments, in worship, in Bible reading, and in prayer. Moreover, just as the temple was, for Jews in Jesus time, a place where heaven and earth overlapped, now we, as individual Christians, are called to be such places of overlap, where the light of Jesus shines through us. It highlights the crucial importance of forgiveness. Just as God has forgiven us our sins, so are we to forgive others. The Lord's prayer is explicit on this point. Becoming a Christian, Wright asserts, is not a matter or accepting certain improbable factual assertions, but rather a matter of trusting in God and accepting our role in unfolding his plan for the world. Rather than being dissected, as in a laboratory, or treated merely as an instrument of historical or linguistic research, the Bible is in fact one of the principal ways in which God addresses us, to prepare us for our role in fulfilling his ultimate plans. It is another place where this world and God's world overlap. Current debates over "literal" versus "metaphorical" ways of reading scripture are, in Wright's view, counterproductive. The Bible eludes these simplistic categories, which should be abandoned. At its core, then, the "faith" to which the Bible calls us is essentially trusting in a God who has revealed himself in history, who has begun, through Jesus' death and resurrection, to redeem the world and transform it into his kingdom, who invites us into to an intimate relationship with him, who demands that we become all that we were created and meant to be, who forgives us when we fall short of that mark, and who invites us to play a significant role in moving forward his plan for the world. For Wright, Christian faith is not just a matter of spiritual feelings that are quite independent of what we say and do. It makes demands upon us that can only be met in the realm of thought and behavior. As C. S. Lewis did in his fiction, "Simply Christian" persuasively invites its readers to recognize that there is a transcendent reality that impinges on our ordinary world, that the God who rules this realm has made himself known in history and continues to do so, that we are part of his plan to renew his creation, and, consequently, that what we think and do has cosmic significance.

Interesting, but no Lewis
Format: Paperback
Some books can be completely conveyed in about eight sentences or a couple paragraphs. This is one of them. Everything else beyond the core thesis is unnecessary or repetitive. This book probably would have made a good article. Wright is a well known Pauline expert, but in this book he takes a step out of his comfort zone. I usually find Paul rambling and confusing enough, so I look to experts like Wright to clarify Paul for me. But in this book, Wright seems to put on his Paul hat and just reiterates Pauline gobbledy-gook. Throughout, he presents long passages comprised solely of Pauline quotes. This book is billed as an updated version of C.S. Lewis’s “Mere Christianity.” Both Wright and Lewis are seeped in their Anglican tradition. But where Lewis looks at the various Christian denominations and identifies what’s common and good among them all, Wright sees differences and insists they are all wrong. In alienating evangelicals on the one hand, and Catholics on the other, Wright suggests that to be Simply Christian you must abandon your faith traditions that are at odds with his. I can’t imagine Lewis taking this tack. I give this three stars, for its clear style, for being thought provoking, and for its call to personal introspection.
